“ Thank you for your reply! I have the original R5. Originally I tried both one shot and servo on still subjects (I rarely shoot action shots), but because I noticed an issue I have been specifically only trying one shot on still subjects and servo on moving subjects. When using one shot I only use the middle AF point and then reframe.. that has always been my preferred method because I don't want to have to choose a new AF point every time my preferred focal point (usually a face) is in a new area of the frame.
When I check in Canon DPP software it indicates that the AF point is in the middle (when the photo was shot in one shot) however it does the same with my DSLR photos when the focus is clearly on the face (that I originally locked focus on before reframing) that is no longer in the middle of the frame, so I assume it is just indicating the AF point I have allocated, rather than where it locked focus? Is there a place where I can specifically see where the focus locked? When looking at images I shot in servo (on moving subjects, during tests) it does indicate that the AF is on the eye, but they are very much not in focus. My colleague also has the R5 and he almost always uses servo too, I believe. “
The AF modes, One Shot and Servo, lock focus in different ways. One Shot locks focus when you half press the Shutter. By default, the camera will also emit a beep. By default, exposure is also locked when focus is locked.
Servo mode behavior is very different because of how it is continuously refocusing for as long as you maintain a half press on the Shutter. Servo locks focus and metering when the shutter fires.
As for the AF point is displayed in the center after you recompose, you are correct. The camera is showing you which AF point locked focus, not necessarily where your subject is located.
Evaluative Metering mode can bias the metering to the location of your active and locked AF point. By default, One Shot will always do this, even when you recompose your shot. Both focus and exposure were locked when the camera beeped, providing you maintain the half press on the Shutter.
When you focus and recompose in Servo some interesting things can happen when Whole Area Tracking is enabled. Start here, but enable Whole Area Tracking. I think of this setting combination as DSLR mode.
Notice how the screenshot shows Whole Area Tracking disabled. That’s DSLR mode for One Shot AF. Enable it for Servo mode, and the camera will track your subject across the frame as you recompose.
The crucial step to making this work is to define an Initial AF Tracking Point. Select the Single Point AF and chose the center. Go back in and select the entire screen area to display the icon in the screen shot.
Now try a focus and recompose with Tracking enabled. A cluster of AF points should remain on the subject as you recompose, providing that you maintain a half press on the Shutter. You will see the same behavior if you use BBF.
When you enable Subject Recognition and Eye Tracking, those clusters of AF points change from a cluster to a dynamic bounding rectangle. With Eye Tracking enabled, a small AF box will appear over the subject’s eye.
